EU (European Union) The European Union is a political and economic union of European states created to promote integration, peace, and cooperation among member countries. It evolved from post‑World War II arrangements and treaties to develop common institutions, a single market, and shared policies across diverse fields. The Union's structure combines supranational bodies and intergovernmental decision‑making to coordinate policies among member capitals.
Origins trace to post‑war cooperation such as the Schuman Declaration, the European Coal and Steel Community, and the Treaty of Paris (1951), which linked the industries of France, West Germany, Italy, Belgium, Netherlands, and Luxembourg. The Treaty of Rome (1957) established the European Economic Community and set out market integration that influenced later treaties like the Single European Act and the Treaty of Maastricht. Enlargement rounds connected the Union to the United Kingdom, Ireland, Denmark, Greece, Spain, Portugal, and later the Nordic countries and post‑Cold War democracies such as Poland, Hungary, Czech Republic, and Slovakia. Crises including the 2004 enlargement, the eurozone crisis, and the United Kingdom European Union membership referendum, 2016 shaped reforms such as the Lisbon Treaty and responses coordinated with institutions like the European Central Bank and mechanisms like the European Stability Mechanism.
Key bodies include the European Commission, which proposes legislation and supervises implementation; the Council of the European Union, representing national ministers; and the European Parliament, directly elected and sharing legislative power. The European Council, composed of heads of state or government, sets strategic priorities. Judicial oversight comes from the Court of Justice of the European Union and the General Court, while budgetary scrutiny involves the European Court of Auditors. Monetary policy for euro adopters is set by the European Central Bank in coordination with national central banks such as the Bundesbank and Banque de France. Decision procedures draw on treaties like the Treaty on European Union and the Treaty on the Functioning of the European Union, employing qualified majority voting, unanimity, and co‑decision (ordinary legislative procedure) among actors including national parliaments like the Sejm and Bundestag.
Membership requires adherence to criteria including democratic governance and rule of law as outlined in the Copenhagen criteria. Accession negotiations are structured into chapters monitored by the European Commission and involve instruments such as the Stabilisation and Association Agreement for Western Balkan aspirants like Serbia, Montenegro, and Albania. Enlargement waves included the 1973 enlargement, 1981 enlargement, 1986 enlargement, 1995 enlargement, 2004 enlargement, 2007 enlargement, and 2013 enlargement. The Union has also managed withdrawals, most notably the United Kingdom withdrawal from the European Union following the Brexit referendum and the subsequent Withdrawal Agreement.
EU law comprises primary law (treaties), secondary law (regulations, directives, decisions), and case law from the Court of Justice. Important legal acts include the Charter of Fundamental Rights of the European Union and legislation on competition enforced against firms like Microsoft and Google under antitrust frameworks. Policies span the Common Agricultural Policy, the Common Fisheries Policy, state aid rules, and cohesion policy administered by the European Regional Development Fund and the European Social Fund. The Union coordinates public health actions involving agencies such as the European Medicines Agency and addresses migration with instruments like the Dublin Regulation and cooperation with organizations such as the United Nations High Commissioner for Refugees.
The single market removes barriers to movement of goods, services, capital, and people across member states, facilitating trade among economies including Germany, France, Italy, and Spain. The eurozone, governed by the European Central Bank, integrates monetary policy for countries sharing the euro; fiscal coordination involves the Stability and Growth Pact and instruments like the European Stability Mechanism and the NextGenerationEU recovery plan. Trade agreements negotiated by the Union include accords with Canada (CETA), Japan (EPA), and partnerships with United States frameworks. Competition policy, digital market regulation such as the General Data Protection Regulation, and initiatives like the Horizon 2020 research programme shape innovation and industry.
The Union conducts external action through the European External Action Service and appoints a High Representative for Foreign Affairs and Security Policy who coordinates diplomacy with partners including NATO, United States, Russia, and China. Common Security and Defence Policy missions have deployed civilian and military operations in regions like the Western Balkans and Africa, cooperating with organizations such as the United Nations and African Union. Sanctions, trade diplomacy, development aid via the European Development Fund, and neighborhood policies such as the European Neighbourhood Policy are central tools in external engagement.
Symbols include the Flag of Europe and the Europe Day celebration on 9 May. Citizenship of the Union confers rights such as free movement, voting in European Parliament elections, and consular protection by other member states' embassies abroad. Instruments like the Schengen Agreement facilitate passport‑free travel for most members, and cultural programmes such as Erasmus+ promote educational exchanges across universities like the Sorbonne and University of Bologna.
